This adds the argparse library [1] as autojump_argparse and imports it via sys.path mangling in case argparse does not exist (Python 2.6 or below without argparse installed).
This makes autojump effectively work with Python 2.6 again by default.
I have not verified license compatibility, but given the intention of the (backport) project this is likely OK (it is licensed under the Python license).
